SPECIFICATION forming part of Letters Patent No. 701,447, dated June 3,1902. Application filed January 14, 1901. .Serial No. 43,164 (No model.)

To (tZZ whom itmrty concern:

Be it known that I, PHILIP H. YAWMAN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Roller Copying- Presses; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being bad to the accompanying drawings, forminga part of thisspecification, and to the referencenmnerals marked thereon.

My present invention relates to roller-copiers or devices forpress-copying letters or other documents upon a continuous web or I5sheet of paper, and has for its object to improve the construction andoperation of said devices whereby they may be readily constructed andassembled and the various adjustments provided for.

The invention further consists in improved connecting devices betweenthe web-reel and the paper-web and in certain improved constructions andcombinations of parts, all as will be hereinafter fully described andthe novel features pointed out in the claims at the end of thisspecification.

In the'accompanyingdrawings, Figure 1 is a longitudinal sectional Viewof a rollercopier embodying my improvementsg'Fig a side elevation of theupper portion thereof;

Fig. 3, a plan view with a part of the lettersupport broken away; Fig.4, a vertical sectional View on the line a a of Fig. 2; Fig. 5, a View,partly in section, of the roller adjusting devices; Fig. 6, a horizontalsectional View on-the line b b ofFig. '5; Fig. 7,a sectional'viewon theline'o c of Fig.5; Fig. 8, a detail viewof the clip or holding devicefor attaching the paper-web to the roll, and Fig. 40 9 a cross-sectionalView of the same.

Similar reference-numerals in the several figures indicate similarparts.

As shown in'the drawings, the copier is fastened upon a suitable tableor support 1, 5 forming a part of or connected to a cabinet 2, inclosingthe reel upon which the paper containing the copied letters is wound,said reel being composed of side plates 3, mounted upon a journal orarbor 4, said plates be- 111g connected by rods 5 to form an open reelpermitting the dampened web to dry readily.

.Upon one end of the arbor 4 is arranged a .pulley (3, (indicated bydotted lines in Fig. 1,)

around which extends a belt '7, connected with the copying or pressingrollers,as hereinafter-described. The table or supportl is provided withtwo apertures 8, through either of which the paper-web may extend to andfrom the reel,as usual in devices of this description. Connected to oneof the cross bars or rods 5 of the reel is a strip of flexiblemateriahas Icloth, (indicated by 9,) having at its upper end adetachable clamping device, to which the paper-web is attachedafterhaving passed from the copier, the said clip or connecting deviceconsisting of a strip ofmetal 1'0, doubled over with and upon the end ofthe strip 9 and having pivotedto the stud 11 thereon a clip or fasteningdevice in the form of a wire 12, having the two parallel spring arms orportions adapted to extend upon opposite sides of the sheet-metal strip10 and prevented from accidental movement by the engagement of one ofthe arms with a slight projection 14: on the side of the plate 10, saidclip being adapted to detachably secure the free end of the paper-webwhen the latter is folded over thestriplO, as shown in Figs. 8- and 9. iY

The body or main frame of the copier con sists of two side plates 15,connected by the cross-rods or braces 16 and each provided with suitableslots or recesses finished or smoothed on the forward and lower sides oredges 17 and'lS, respectively, forming ways for suitable bearing-blockson which the various rollers are mounted; Extendingrearwardly over theways or surfaces 17 are overhangingarms l9,preferablyforked or recessedat the ends, as shown, for the reception of the go forward edges of the.filling pieces or plates 20, the rear edges of said plates 20 beingmovable in and held from lateral movement by ways formed by flangesorlugs 21 on the rear sides of the openingsin the side plates. The lowerends of the filling pieces or plates 20, when the latter are in place,are guided and held from lateral movement by suitable lugs orprojections 22, formed at the lower portions of the apertures in thesides 15. The forward edges of the filling-pieces are fin ished andextend substantially parallel with the finished edges or surfaces 17 andform ways for the bearing-blocks carrying the rollers, as will bedescribed, and the lower portions of said filling-pieces are finishedand smoothed, as at 23, to form ways for other bearing-blocks locatedbetween said surfaces and thelower finished surfaces 18. As usual indevices of this description the paper upon which the copies are to bemade is contained in a roll 24, arranged upon a shaft loosely journaledin the sides of the casing, and from this the paper extends beneath animmersing-roller 26, located in the water-pan 27, and then extendsupward between the wringingroller 28 and the lower pressing or copyingroller 29, passing partially around the latter and between it and theupper pressing or copying roller 30, thence over the roller 31, havingthe flexible rubber strips 32 projecting radially therefrom, and thendown into the casing or cabinet, where it is attached to the reel, asdescribed.

33 indicates a removable letter support or plate restingloosely uponsuitable adjustable supports, such as screws 34. (See Fig.1.) The lowerpressing-roller 29 is provided with journals at its ends rotatingloosely in journal boxes 35, arranged between the surfaces 17vand theforward edge or surface of the filling-blocks 20 and is preferablycomposed of unyielding material, such as hard rubber. Resting upon theupper sides of the bearingblocks 35 are pins 36, held loosely insuitable recesses formed in the bearing-blocks 37,

-' jtheir upper surfaces.

. copier is not in use.

in which latter the journals of the upper pressing-roller 30 are looselymounted, said bearing-blocks 37 operating in the vertical ways and beingprovided at their upper sides with pins 38, entering vertical aperturesformed .in bearing-blocks 39, the latter being also vertically movableand operated downwardly by set-screws 40, passing through theoverhanging arms 19 and contacting with Journaled loosely in thebearing-blocks 39 are the ends of atransversely-extending spindle orarbor 41, having an operating bail or handle 42 and provided near theends with radially-extending slots or grooves cut away eccentrically toform the cams or eccentric portions 43, as shown in Figs. 5 and 7, andin the cut-away portions thus formed project the upper ends of the pins38 on the journal-blocks 37 of the upper pressing or copying roller.

44 indicates springs encircling pins 36, arranged between thebearing-blocks 35 and 37, as shown in Fig. 5, so as to raise the roller30 out of contact with the roller 29 when the The pins 38, projectinginto the slots formed in the shaft or spindle 41, prevent endwisemovement of the latter in its bearing-blocks and form a cheap andsuitable adjusting device for the upper pressing-roller. The inner sidesof the bearingblocks 35,!37, and 39 are flanged, as usual, as indicatedin Fig. 7, to prevent their outward movement, theirinward movement beingprevented by the rollers themselves. The wringing-roller 28 is providedat its ends with studs or spindles loosely operating in journal orbearing blocks 45, resting upon the ways or surfaces 18of the frame andmovable between the latter and the surface 23 of the fillingblocks 20.

46 indicates blocks or plates guided upon ways 18 and 23 and preventedfrom rearward movement by lugs 47, arranged between the ends of saidways and the recess or aperture 48.

49 indicates a set-screw having an operating-head in the recess 48 andextending. through the block 46 and operating against the bearing-blocks45 to operate'the squeezing or wringing roller against the roller 29with greater or less pressure, as may be desirable or necessary.

The filling blocks or pieces 20 are guided to move vertically in theside frame, but are held normally in the position shown in Fig. 5 byheads of screws 50, operating in said side frame, one side of the headsof said screws being cut away, as at 51, to permit the removel of saidfilling-blocks when said cutaway portion is turned into line with therear edges of the filling plates or blocks.

The roller 31 is provided at its ends with journals operating in thelower ends of open bearing-slots 52 and is also provided at one end witha pulley 53, around which extends a belt 54, preferable formed of aspiral spring, said belt also passing around the grooved pulley 55,secured to the end of the shaft of the roller 29. On the inner side ofthis pulley 55 is a ratchet-wheel 56, with which cooperates agravitating pawl 57, pivoted on the side of the casing and preventingbackward rotation, and on the outer side thereof are provided internalgear-teeth 58, with which meshes a pinion 59, formed upon or secured toa short shaft or stud 60,'jonrnaled in the bracket 61 on one of the sideframes and having an operating-handle 62. The object of embodying theinternal gear and the pinion is to provide a comparatively slow motionfor the rollers and yet permit the crank to rotate in the samedirection. The rear end of the shaft of the roller 29 is provided with apulley 63, around which extends the belt 7, connected to the paper-reel.

The operation of the device as a whole is not essentially different fromthat of the device shown in the patent to .lewel,.No. 416,628. Theletter to be copied being placed in the pan 27, the handle is operatedin the direction indicated by the arrow in Fig. 2, thesurplus waterbeing wrung or squeezed from the web of copying-paper and the manuscriptfed from the support 33 and upon the damp web,

between the pressing-rollers 29 and 30, and

thence the copying-web extends to the reel,

which is slowly rotated by the means described.

The amount of pressure exerted between the pressing or copying rollersmay be varied by the adjustment of the eccentric spindle or shaft 41,the forward movement of the bail or handle to the position shown in Fig.5 forcing the upper pressing-roll downward against its spring and themovement of the handle or bail 42 to the rear will release the pressure,al lowing the rolls to be separated by the spring. By the operation ofthe adjusting-screws 4-0 the parts are adjusted, so that when the bail42 is swungforward the maximum pressure desired will be given, and whenit is swung to the rear the pressing-rollers will be spread far enoughby the springs 44, so as to prevent their becoming flattened when not inuse.

By the employment of the bearing-surface on the side frames as describedand the filling-piece 20 I am enabled not only to manufacturethe copiersmore readily, as the surfaces to be finished are readily accessible; but

by the removal of these pieces 20 each of the journal boxes or blocks isaccessible and may be removed for repair or adjustment without thenecessity of taking the whole machine apart.

The location of the cam-shaft 41 in the bearing or journal boxes andproviding the pins in the boxes with which the cam-grooves engage alsosimplifies the construction and enhances the appearance of the device.
